IMPROVEMENT IN ANIMAL-TRAPS.

Specification forming part of Letters Patent No. 14,l63, dated September15, 1864.

To all whom it may concern.-

Be it known that I U. HARMoN DUPARCK, ot' the town of Albion, county ofCalhoun, and State of Michigan, have invented a new and useful machinefor trapping game, called a Game-Trap 3 and Ido hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation ot' the same, reference being had to the annexed drawings,making a part of this specification, in which- Figure l is a perspectiveview Fig. 2, the bottom board, showing the drop-door A, the treadle B asattached to the spring trigger H', and the tipping board C. Fig. 3 isthe dropdoor, with chain G attached to hook onto lever D. Fig. 4 is thetipping board O, hung on balance-pin I, the longest end resting on thebottom of the trap, except when the game passes the balancepin I, andthe staple at the short end ofthe tipping board, to which is to behooked the chain F. Fig. 5 is lever D, showing post E and chains F and Gand pin K on lever D. Fig. 6 is the treadlc B as attached tospring-trigger H. Fig. 7 is the top board of trap, showing the lever Dand post E and spring-trigger H.

The game-trap is constructed as follows As shown in Fig. l, it is anoblong box, inclosed on all sides, with an opening at the end of oneside, in which slides up and down the drop-door A. It is divided by twopartitions into three compartments. The game enters the tirstcompartment by the opening aforesaid, the drop-door being up when thetrap is set. In the trst compartment is the treadle B, to which the baitis fastened. The treadle B is attached to a spring-trigger, H, which,when the trap is set, hooks onto a pin, K, on lever D. When the animalsteps on the treadle B, it unhooks the spring-trigger H from the pin Kon lever D, and thel drop-doorA at the end of the lever D falls. Thesecond compartment is a passa geway from the first into the third, inwhich is a tipping board, (l, with its long end resting on the bottomot' the trap at the entrance from the tirst compartment, and its shortend reaching nearly the top ofthe trap over the entrance to the thirdcompartment. The tipping board hangs near its center on a balaneepin,and when the animal leaves the first compartment and passes thebalance-pin the tipping board tips down and opens the entrance to thethird compartment. The short end of' the tipping board is attached tothe lever D, at the endv opposite the drop-door aforesaid, by a chain,F, and when the animal reaches the short end of the tipping board, aboutto enter the third compartment, his weight brings down that end of thelever D and raises the drop door attached to the opposite end ot thelever D, and at the same time the pin K on lever D, near the endopposite the drop-door, passes under the hook on the spring-triggerattached to the treadle B, and thus sets the trap as the animal entersthe third compartment. When the animal steps oft the tipping board, onentering the third compartment, the tipping board falls back toits firstposition, closing the entrance to the third compartment and securing theanimal, while the trap is at the same time set for catehin g another.

What I claim is- The attachment ot' the tipping board C to the lever D,by which the Weight of the animal on the tipping board C, as he passesinto the third compartment, raises the dropdoor A and hooks the pin K onlever D over the springtrigger H, attached to treadle B, and thus setsthe trap.
